I agree, mixed mode is kind of weird, but its expected for me because it lacks arab/north african components to seperate euro from other ethnicities for example.
but percentage wise its very accurate. Except for my black african maybe.. I think my Ethiopian gets misread for Arab/Middle eastern, same with my North african. And since Oromo ethiopians are if im not mistaken blacker than other types of Ethiopians, like Tigray, or Amhara then i dont understand why most gedmatch tests give me only 25% black african percentage wise, but 33%> black african in mixed oracle. very weird.
